Ubiquitous environments such as Vehicular Ad Hoc Networks need applications that allow them to integrate data and services to build knowledge that can be used to make decisions and to improve standards of living and user safety, among others. We have designed a collaborative virtual environment that covers the needs of integration of knowledge from different vehicles to endow the final user with the necessary information. This environment has been carried out following a model-driven approach that generates a groupware application for improving collaborative work and access to services. The implemented tool facilitates the development and implementation of collaborative frameworks in VANETs, where every vehicle acts as a node.
